[Python-ideas] Relative Imports

[Chris Barker - NOAA Federal]

This is somewhat unpleasant to me, especially while developing something
and trying to test it quickly.
I just want to be able to use same relative imports and run single file
with `python3 test_main.py` for example.


I had the same frustration when I first tried to use relative imports.

Then I discovered setuptools’ develop mode (now pip editable install)

It is the right way to run code in packages under development.

-CHB


Running files as modules every time is tiring. This is my problem.
I could not come up with a concrete solution idea yet i am thinking on it.
Open to suggestions.

Thank you all for your help!
